Reclassification across risk groups defined as <6%, 6% to <20%, ≥20% for heart failure (HF) and defined as <5%, 5% to 15%, ≥15% for atrial fibrillation (AF). Numbers in the cells refer to numbers of observed events during follow-up over the total number of individuals in each combination of categories.
